Unable to display real time data in GUI.

Hi,I am transmitting data from STM32CubeIDE to MATLAB ,reading successful data and graph in MATLAB. But when trying to display this data in GUI,not getting graph in GUI instead of that it shows graph in MATLAB. In GUI,i am just running the MATLAB file by using command "run('MATLAB file name')",is this right or wrong? When i run matlab file in GUI which contain fixed data means 50 samples of data then it shows right graph in GUI.
